Abstract
Abstract Compositions in the form of an aqueous solution comprising: (a) a compound of a preservative metal; (b) a branched-chain carboxylic acid or a dipentene-mono-carboxylic acid or a dipentene-di-carboxylic acid; and (c) ammonia and/or an ammonium compound, the amount of ammonia and/or ammonium compound being at least sufficient to solubilize the compound (a) and to neutralize the acid (b), are useful for the preservation of wood and like materials by impregnation into or surface application to the material and are also useful as fungicides for the treatment of plants for agricultural and horticultural use.
